This tool is packed with enough features to make you feel like the CEO of Boss Drilling. It makes drilling perfectly centered holes in tubes as easy as clamping it in a vise and using a hand drill to run the bit through the bushing guides. Around here we typically prefer a stub length carbide like this one here. It allows you to go full send without having to worry about poking the drill out of the other side of the tube.

• Built in offset scale from bottom bracket center to the first bottle boss (Boss A dimension on the respective tube in BikeCAD see image below). The tool supplied as standard with the BB dummy measure arm covers this range from 50mm-245mm. We can make custom lengths and you can also use this tool without the arm for tricky or unique boss locations.

• Flippable BB dummy that simulates 1.5” (BSA) or 2.0” (T47) the most common OD’s for Bottom Brackets.

  • Included with this design is also a vertical BB adjustment with the most common Downtube and Seattube sizes machine engraved into the adjustment arm.

• FARR Signature Brass “Get a Grip” plates to protect the rest of the tool when clamping in a vise.

• Replaceable precision aligned 1/4” Drill Bushings (although you can likely drill 1000’s of bosses before they need to be swapped)

• Tool-Free Tube Clamping Mechanism For quick loading and swapping of tubes.

• Laser/Machine Engraved notes for hex size and reminders/encouragement when using the tool.

Additional Notes:

• Cosmetic Blem units usually have minor ‘hazing’ on one of the laser etches or dents or dings from shipping to/from the anodizer. You can always reach out for images of the exact issue prior to purchase.

• Custom finishes are one-of-a-kind and take about 4-5 weeks to turn around from the time of the order. The options are basically unlimited and if you have an idea we can make it happen. We also have a ton of “stock” custom finishes that we do on repeat. If you are interested in one of those or would like to see pictures, please reach out.
